Polystyrene is one of the most commonly used thermoplastic plastics,transparent and with the translative temperature higher than 100 degrees Celsius. But it is not easy to decay and degraded by recycle polystyrene natural microbes, becoming the white pollution. So the polystyrene foam recycling is of great necessity.

Why volume reduction?

All kinds of polystyrene foam can be recycled and reused by different methods. But most polystyrene products are currently not recycled due to the lack of incentive to invest in the compactors and logistical systems required. Generally, polystyrene can not be recycled by curbside, Due to the low density of polystyrene foam; it is not economical to collect. As a result, manufacturers cannot obtain sufficient scrap, so polystyrene foam recycling is a business of great potential.

However, if the waste material goes through an initial compaction process, the material changes density from typically 30 kg/m3 to 400 kg/m3 and becomes a recyclable commodity of high value for producers of recycled plastic pellets. The recycling of it has been improved a lot in industry, turning up many new ways for compacting it.
